Reactjs - error loading translation files

Question

I've been trying to start a new react project to practice some skills.

And recently I tried to add internationalization and localization, by adding react-i18next and i18next.

Simply followed the step by step guide available on https://react.i18next.com and added my translation files.

But when I run the project I get the console error GET https://localhost:8080/locales/en/generic.json 404 (Not Found)

At first I thought that the project was missing a json-loader so I added to the webpack.config.js, but the result is the same. I check the paths and all seems right.

Thanks in advance

i18n file

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';

import Backend from 'i18next-http-backend';
import LanguageDetector from 'i18next-browser-languagedetector';

const fallbackLng = ["pt"];
const availableLanguages = ["pt", "en"];

const backendOptions = {
  loadPath: "/locales/{{lng}}/{{ns}}.json",
  crossDomain: true
};


i18n
  // load translation using http
  .use(Backend)
  // detect user language
  .use(LanguageDetector)
  // pass the i18n instance to react-i18next.
  .use(initReactI18next)
  .init({
    backend: backendOptions,
    fallbackLng,
    detection: {
      checkWhitelist: true,
    },
    whitelist: availableLanguages,
    interpolation: {
      escapeValue: false // react already safes from xss
    },
    ns: [
      "generic"
    ],
    defaultNS: "generic",
  });

export default i18n;

root file

import './i18n';
import { I18nextProvider } from 'react-i18next';
import i18n from './i18n';


const App: React.FC = React.memo(() => {
  return (
    <AppContainer>
      <I18nextProvider i18n={i18n}>
        <Router>
          <React.Suspense fallback={<div>Loading...</div>}>
            <MainContainer />
          </React.Suspense>
        </Router>
      </I18nextProvider>
    </AppContainer>
  )
});

ReactDOM.render(<App />, document.getElementById('root'))

So I think that o discovered a solution

All I did was add the copy-webpack-plugin and put the following code to my webpack file

const common = {
  ...
  plugins: [
    ...
    new CopyPlugin([
      { from: "./src/locales", to: "locales" },
    ]),
  ]
}
